1 Claim.

This invention relates to toilet seat hinges, and more particularly to an improved double hinge which is especially adapted for connecting a toilet seat and cover to a closet bowl.

One object of this invention is to provide a pair of double toilet seat hinges of the above nature, each having a hollow short tubular hinge pin which is detachably mounted in the hinge post and sockets formed in the seat and cover hinge leaves, thus eliminating the long hinge tube commonly employed for connecting the hinges at both sides of the seat.

A further object of this invention is to provide an improved toilet seat hinge of the above nature which will be relatively inexpensive to manufacture, simple in construction, compact, ornamental in appearance, and very efficient and durable in use.

With these and other objects in view, which will appear as the description proceeds, there has been illustrated in the accompanying drawing one form in which the invention may be conveniently embodied in practice.

In the drawing:

Fig. 1 is a side elevational view of a toilet seat and cover shown hinged to a toilet bowl by a double hinge embodying the features and principles of this invention.

Fig. 2 is a broken top plan view of the parts shown in Fig, 1.

Fig. 3 is an enlarged sectional view of one of the hinge units shown in Fig. 1 taken on the line 33 of Fig. 2,

Fig. 4 is an exploded view of the double hinge unit showing the relationship of the separate parts thereof.

Referring now to the drawing wherein like reference numerals designate like parts throughout the several views, the numeral I denotes a standard form of toilet bowl of porcelain or the like, to which a seat I I and a cover I2 are swingably connected by the improved double hinge of this invention. In this instance, twosets of double hinge units are used which are similar to each other in every respect except that one is right-hand and the other is left-hand." Each hinge unit includes an identical supporting post I3, a long curved leaf I 4 adapted to be secured to the underside of the cover I2 by screws I5 and upwardly offset to clear the top of the seat II, and a short curved leaf I6 oifset downwardly to embrace and be secured to the underside of the seat II by screws I l.

The post I3 is providedwith a circular intermediate flange I8 from which extends downwardly a vertical threaded shank I9 which is adapted to be passed through a hole in a lip 28 provided on the bowl II]. A washer 2|, preferably of rubber, is located on the shank I9 between the flange I8 and the lip 20 of the closet bowl II A like washer 22 is also provided on the shank I9 under the bowl I 0 between said lip 20 and a metal washer 23, said washers being held tightly in position by means of a nut 24 screwed upon the lower end of the shank I9 of the post I3. The upper part of the post I3 curves upwardly and forwardly from the flange I8 and terminates in a hollow apertured boss 25, having a cylindrical bore 26, the axis of which is disposed at right-angles to the vertical axis of the post I3, and which is located in a plane spaced forwardly therefrom.

The short seat-holding leaf I6 is provided at its rear end with a vertically upstanding arm 21 which terminates in a counterbored boss 28 having a socket29 therein, which socket is equal in diameter to that of the aperture 26 of the hollow boss 25 on the post I3. The socket 29 is closed at its outer end by a conical base shoulder 30. By means of this construction it will be seen that the seat-holding leaf I6 is offset downwardly from the axis of the aperture 2% and extends forwardly substantially at right-angles thereto.

Th long cover-holding leaf I4 is provided on its lower end with a downwardly curved arm portion 3I (see Fig. l) which terminates in a counterbored boss 32 forming a socket 33, which has the same diameter as the aperture 26 of the boss 25 on the post I 3 and the socket 29 of the seat-holding hinge leaf IS. The socket 33 is closed at its outer end by a conical base shoulder 34. The cover-holding leaf I4 is slightly offset from the axis of the bore 26 and extends forwardly substantially at right-angles to said axis.

The hinge parts comprising the post I3, the long leaf I4, and the short leaf I6 are connected together to form a unit by a hollow hinge pin 35, herein shown as a short length of substantially thin-walled metallic tubing. The length of the hinge pin 35 is such that its ends abut the shoulders 30 and 34 in the bosses 2B and 32 respectively of the short and long I4, when said bosses 28 and 32 are in abutting relation with the opposite sides of the center boss 25 on the supporting post I3 (see Fig. 3). The parts of the hinges are held in assembled relation upon the seat II and cover i2, as shown in Fig. 2, by screws I5 and I! respectively.

hinge leaves I6 and One advantage of the present invention is that the posts 13 for'each of the right and left hinge units are identical; and the same is true of the hollow hinge pins 35, thus greatly facilitating the manufacture of this article and keeping the cost down to a minimum. A saving of metal is also achieved through the elimination of the usual long tube connecting the pair of hinge units.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure, but may be embodied and modified in various other forms without departing from its spirit. In short, the invention ineludes all the modifications and embodiments coming within the scope of the following claim.

Having thus fully described the invention, what is claimed as new and for which it is desired to secure Letters Patent, is:

'In a double hinge for a closet bowl seat and cover, a post adapted to be secured to the closet bowl, a short leaf adapted to be secured to said seat, a long leaf adapted to be secured to said cover, and a strong, stiff thin-walled hinge tube comprising a short length of metal tubing of relatively large diameter extending through said 7 post and having its ends seated in sockets formed on said long and short leaves which are located on opposite sides of said post.
